General Motors is recalling 92,221 full-size trucks and SUVs for a defect in ignition lock systems that can cause safety problems. In affected vehicles, the actuator isn’t the right size, which could cause the ignition to get stuck in the “Start” position, and then either due to a jarring event or a cool interior temperature the ignition could switch back to the “Accessory” position. Doing so would cause a loss of power assistance and the airbags might not deploy. This is a different ignition issue than the one that’s been ongoing for the past year. This past Thursday’s recall covers certain 2011-2012-models and certain 2007-2014-models that were repaired with defective parts. The recall is for U.S., Canadian, Mexican and exported vehicles. The affected models are Chevrolet Silverado light-duty and heavy-duty pickups; Avalanche, Tahoe and Suburban; GMC Sierra light duty and heavy-duty pickups; and Yukon and Yukon XL; Cadillac Escalade, Escalade ESV and Escalade EXT. GM says the ignition lock actuators may be too wide, making turning the key difficult when it’s hot inside the cab. No crashes or injuries have been reported. Last year, GM recalled 2.6 million small cars for defective ignition switches, linked to at least 42 deaths and 58 injuries.
